'Be it known that I WILLIAM I-I. ARM- s'rnone a citizen of the UnitedStates, and

a resident of Plainfield, Union County,fand State ofNew Jersey, haveinvented a certa n Mechanical Tie Tamper, ofzwhich thegfol- V lowing is;a specification accompanied by I in part pointed out hereinafter.

This invention relatesto tie tampers and more particularly to'aj formfoftie tamper.-

adapted to be operated manually.

An object of'this invention is to apply greater, power fortampingrailroad tiesand to enable'the operator to'conviently apply such power.Other objects and advantages of the invention will be in part obviousand provided with teeth D to gripthetie and prevent the shoe A from.slipping easily thereon. At either side of the shoe'A a pair of uprightbearing members E and F are preferably formed integrally with the shoe Aand adapted to support apair of curved tamper bars G and H provided withbroadened ends J adapted to push therock or other ballast material undera tie K.- The tamper i is supp bar Gis supported on the upright bearingmember E by means of a linkL and a bell crank O pivoted to the bar Gbymeans of pins P and Q. Similarly the tamper bar H orted on the uprightbearing member F by means of a-link R and a'bell crank S being pivotedto the bar H by th U respectively; The link L is provided with a'pivotal connection V at the bearing member E.

With suitable ballast material adjacent the bottom of the f tie Kthe lever Z- is pulled,longitudinally to the left forcing the tamperbars G and H downwardly and inwardly to drive the ballast material underthetie K.
